The Alcon LADARVision 6000 excimer laser was recalled by the US Food and Drug Administration due to a major defect in its ablation pattern that could lead to central islands. It is my understanding that the US and Canadian versions are exactly the same, however I may be wrong and/or the Canadian version may have had upgrades to resolve the problem. The Alcon LADARVision 4000 does not have the central island problem.

Hello
Yes i am glad i found this site! The Alcon Ladar6000 Custom Cornea System the same as you are talking of? they say its the latest generation of technology approved for full range of wavefront treatmens by the FDA and they say they are the first and only centre in canada to offer this remium technology. This is a very very highly respectable Cornea surgeon.
This along with the IntraLase? mmmm...
now you have me wondering !
